A gist to add a user to the Alpine docker image

alpine-user.Dockerfile

FROM alpine:3

ENV USER_ID=65535
ENV GROUP_ID=65535
ENV USER_NAME=rsync-user
ENV GROUP_NAME=rsync-user

RUN addgroup -g $GROUP_ID $GROUP_NAME && \
    adduser --shell /sbin/nologin --disabled-password \
    --no-create-home --uid $USER_ID --ingroup $GROUP_NAME $USER_NAME

USER $USER_NAME

At line 8, shouldn't it be:

RUN addgroup -g $GROUP_ID $GROUP_NAME && \

instead of

RUN addgroup -g $USER_ID $GROUP_NAME && \

Thanks, you are right, I updated it.
